Nitrogen is a part of chlorophyll Essay Example for Free

Nitrogen is a part of chlorophyll Essay Experiment- Using the fertilizer is important for many gardeners as it helps their plants to grow strong and healthy plus fertilizers can be fairly expensive and not all work as predicted, also Gardeners only get one chance at either growing their crop or plants so it is essential for them to get the fertilizer right. This experiment will focus on 6 major fertilizer brands to find out which is the best- Research- Nitrogen (N) Nitrogen is a part of all living cells and is a necessary part of all proteins, enzymes and metabolic processes involved in the synthesis and transfer of energy. Nitrogen is a part of chlorophyll, the green pigment of the plant that is responsible for photosynthesis. Helps plants with rapid growth, increasing seed and fruit production and improving the quality of leaf and forage crops. Nitrogen often comes from fertilizer application and from the air (legumes get their N from the atmosphere, water or rainfall contributes very little nitrogen) Phosphorus (P) Like nitrogen, phosphorus (P) is an essential part of the process of photosynthesis. Involved in the formation of all oils, sugars, starches, etc. Helps with the transformation of solar energy into chemical energy; proper plant maturation; withstanding stress. Effects rapid growth. Encourages blooming and root growth. Phosphorus often comes from fertilizer, bone meal, and superphosphate. Potassium (K) Potassium is absorbed by plants in larger amounts than any other mineral element except nitrogen and, in some cases, calcium. Helps in the building of protein, photosynthesis, fruit quality and reduction of diseases. Potassium is supplied to plants by soil minerals, organic materials, and fertilizer. Calcium (Ca) Calcium, an essential part of plant cell wall structure, provides for normal transport and retention of other elements as well as strength in the plant. It is also thought to counteract the effect of alkali salts and organic acids within a plant. Sources of calcium are dolomitic lime, gypsum, and superphosphate. Nitrogen, Phosphorus, Potassium and Calcium are all the essential nutrients usually added to help aide in the plants growth as when the plant grows it absorbs large proportions of each nutrient meaning that there will be near to none left, ending in a stunted growth, Gardeners and farmers add these nutrients to the ground to ensure there will always be enough for when the plant grows, the acidity of the soil is another reason why nutrients are added because the higher the acidic level of the soil the more nutrients will be lost. All fertilizers have a controlled release which ensures that they will last longer. Information on Fertilizers used- Urea- Urea has the highest concentration of nitrogen that a fertilizer can offer, it is composed of 50% Nitrogen, as it is usually Nitrogen that is absorbed the most by plants during growth. It is one of the basic fertilizers as it only offers one nutrient to the plants. Osmocote- Osmocote offers the most diverse and wide range of nutrients to plants, Osmocote is composed of Nitrogen, Sulphur, Phosphorus, Potassium and Calcium and also contains organic seed growing mix to help with faster seed growth. It also contains a wetting agent which ensures that it will stay moisturized for longer. Nitrophoska- Nitrophoska is the most environmentally friendly of all the fertilizers as the components wear off over a certain time into the soil leaving no traces or harm to the environment, it also is one of the few fertilizers that can be used on any plant. Nitrophoska contains Nitrogen, Phosphorus and Potassium. NPK Fertilizer- NPK fertilizer is the most commonly used and manufactured fertilizer as it contains the three essential nutrients for plant growth Nitrogen, Potassium and Phosphorus. Due to its high domestic demand many plants are also able to have NPK Fertilizer used on them. Blood and Bone- Blood Bone Based Fertilizer contains 65% blood and Bone meal with added animal manure (Nitogen-5. 4: Phosphorus4. 0: Potassium-0. 4). Blood and Bone contains the most organic matter of all the fertilizers, which gives the plant a larger leaf growth and can be used on a wide range of plants and trees. Control- A controlled test with only garden soil and no fertilizer to test and compare to the other fertilizers. Why choose Granular? Another important thing that needs to be discussed is why use Granular fertilizer out of a whole range of other fertilizer types. Reasons- Granular fertilizer can be weighted or measured more easily to ensure that one test doesn’t receive more fertilizer then the one next to it. Granular fertilizer is the cheapest form of fertilizer and it is ideal for indoor and pot plants. Granular fertilizer contains the most nutrients that a fertilizer can offer giving it the advantage over other fertilizers and saving on buying extras, Granular fertilizers also come wetting agents which ensures that it has water for longer. Granular fertilizers are much less harmful as they don’t contain micro bacteria or other harmful substances. And Granular fertilizers offer the widest variety to choose from giving the buyer of an option of what type of fertilizers to buy and which ones will suit their plants. Granular fertilizers are also time released, meaning that it allows nutrients to flow out of the granules and into the soil over time, meaning that the plant will have a constant supply of food and nutrients. Granular fertilizer were chosen to be used for this experiment as they offered a wider variety of advantage for plant growth, to wetting agents and that it was easiest to measure/ weight to give a fairer test.

The Portrayal of Women in Homers Odyssey Essay -- The Odyssey by Home

Does Homer exhibit gender bias in the Odyssey?   Is the nature of woman as depicted in the Odyssey in any way revealing? Upon examining the text of the Odyssey for differential treatment on men and women, it becomes necessary to distinguish between three possible conclusions.   One, differences in treatment reflect the underlying Homeric thesis that   women are "different but equal in nature,"   Two, different treatment   of men and women in the text reflect a thesis that women are "different and unequal in nature" -- arguments about misogyny fall in here but a host of other interpretive possibilities are possible too. Three, the different treatment reflects simple ignorance. How much do we attribute what we discover to male authorship -- or female authorship? In beginning, we might look to the gods for a clue. The adultery between Ares and Aphrodite for example is evenly represented -- both parties are to blame -- both are shamed -- both are banished. Although there is some "locker room talk" between two of the male gods that they would willingly lie in chains several layers thick to be beside Aphrodite.   Sexuality among mortals is another key to this poem and this question. Women and men are represented differentially in this regard -- The herdsman Eumaios -- Odysseus brother by "adoption" recounts how he came to Ithaka a captive of a slave woman Phoinikia -- a woman who had been seduced by a roving seafarer w... .... 17-27.

Internet gambling Essay

This document will inform you about the history of internet gambling, the existing issues, and a number of concerns involved with online gambling. Prior to the launching of the World Wide Web in 1993 which changed the setting of gambling, people had to travel great distances to gamble. The world’s first virtual online casino, Internet Casinos, Inc. (ICI) commenced operation on August 18, 1995 with 18 different casino games. Most of these online gambling companies are located outside of the U. S.to avoid government prosecution. ICI operates out of the Turks and Caicos Islands (Kish, 1999). One of the main reasons internet gambling started was because of costs. The value to start up an internet gambling site is around 1. 5 million dollars, which is half of what it costs to actually construct a casino. ICI estimates that the company averages about a twenty four percent profit margin, versus the typical United States casino, which ranges from eight percent to sixteen percent of each dollar wagered (Kish, 1999). An estimated twenty million people are currently online with a projected 160 million online by the year 2020. The overall market for online gambling is estimated to be approximately $49 billion worldwide (Kish, 1999). The history of internet gambling is only a decade old, however, its history will hold on for several more. There are several existing issues facing internet gambling. The first issues we will discuss are how to regulate internet gambling. The question raised by the emergence of Internet gambling is whether old laws–based mainly on a world of atoms–are still viable, and if not, in which way the Internet should be regulated (Walther, 2000). Some scholars believe that internet gambling needs to be regulated, and of course there are those that say let the owners of the sites regulate themselves. Regulatory procedures can be targeted at either or both of the providers and the consumers of gambling services. In the case of consumers, regulation is usually implemented by age, through prohibition of the participation of minors. Procedures might also be contrived to prohibit problem gamblers or undischarged bankrupts from engaging in gambling (Clarke, 2000). Another existing problem with internet gambling is The Wire Act which was intended to assist the states, territories and possessions of the United States, as well as the District of Columbia, in enforcing their respective laws on gambling and bookmaking and to suppress organized gambling activities. Subsection (a) of the Wire Act, a criminal provision, provides: â€Å"Whoever being engaged in the business of betting or wagering knowingly uses a wire communication facility for the transmission in interstate or foreign commerce of bets or wagers or information assisting in the placing of bets or wagers on any sporting event or contest, or for the transmission of a wire communication which entitles the recipient to receive money or credit as a result of bets or wagers, or for information assisting in the placing of bets or wagers, shall be fined under this title or imprisoned not more than two years, or both† (Rodefer, 2003). During the House of Representatives debate on the bill, Congressman Emanuel Celler, Chairman of the House Judiciary Committee stated â€Å"[t]his bill only gets after the bookmaker, the gambler who makes it his business to take bets or to lay off bets. . . It does not go after the causal gambler who bets $2 on a race (Rodefer, 2003). What the government is having a problem with is that most internet gambling sites are run ran in foreign countries, and they cannot enforce this act against them. What they are trying to do is change the act to include these third parties. An example of this is the introduction of the Internet Gambling Prohibition Act of 1997 (Walther, 2000). The bill would have prohibited Internet gambling by extending the Wire Act’s prohibitions on traditional forms of gambling by phone or wire to the Internet (Walther, 2000). This amendment would provide penalties for online bets and wagers. This so far seems to be the best solution, however ethical and moral dilemmas still rest in the hands of our lawmakers today. The next issue facing internet gambling is taxes. This seems to be the government’s biggest issue. This is because of the billions of dollars we mentioned for profit by these online sites, government can gain significant amount of money from it. The legalization of Internet gambling may cause states to lose some revenue generated from legalized gambling operations because many gamblers would spend their money online (Lassani, 1998). Moreover, states lose revenue by not being able to tax gamblers who win over the Internet. Gamblers who win over the Internet have an incentive not to pay taxes on their winnings because the Internal Revenue Service (IRS) lacks the resources to track online gamblers (Lassani, 1998). The likelihood of addiction to Internet gambling among both children and adults is an extremely important concern. In relation to addiction, children are more likely to become addicted to something new than adults (Smith, 2004). For example, the video game-like nature of virtual casinos, labeled the â€Å"crack cocaine of gambling,† could make online gambling a temptation difficult to resist. Furthermore, the fact that the Internet gambler need not leave the comfort and privacy of his or her home could mean that an individual might become easily addicted. This is the worst thing about internet gambling, because there will not be anyone to detect if a person is addicted or not. Consequently the only aid they will get is their selves, and that leaves the player defenseless against the dependence of gambling. Having to go to the casino to gamble has better chances of knowing who is addicted and who is not, they have hired hands to detect this problem, unlike the home atmosphere. Kevin O’Neill, Deputy Director of New Jersey’s Council on Compulsive Gambling says â€Å"The real threat comes from the isolation and secrecy of the betting activity itself. † â€Å"I call this threat the cave syndrome due to the gambler’s isolated behavior and hidden activity† (Wharry, 2001). In closing the short lived World Wide Web as created pandemonium with our lawmakers. The dilemma of how everyone interprets the Wire Act is a major concern. The efforts to amend it to make all users liable for using the websites are tiresome, and stopping foreigners from creating internet gambling sites seems never-ending since the United States cannot control them. In just over a decade there are over twenty million users, expected to increase to 160 million in the next 14 years. Its revenue is over 49 billion dollars and increasing. There are more profit margins with online gambling than the traditional casino. The cost to create a gambling web is 1. 5 million dollars compared to the 300 million to build a casino, this creates profit and increases attendance because of its trouble-free access. One important concern with internet gambling is addiction. Children are easily addicted to new things than adults and it will make it harder to control and detect gambling addiction. Internet gambling is a good creation for those people who can control themselves, but for those who cannot have a greater chance to end up bankrupt. Thus we can see from this example alone, why lawmakers are having such problems to secure the problem, do they let it carry on or let people put themselves in jeopardy of losing everything. Michael Bolcerek the President of The Poker Group said, â€Å"It’s a personal liberty issue with regard to how you spend your money and what you see over the Internet†(Roth, 2006).

Stopping Binge Drinking on College Campuses - 726 Words

Fact or Fiction â€Å"Getting Serious about Eradicating Binge Drinking,† a text written Henry Wechsler was first introduced to me in my English 102 class. In this Essay Wechsler brought to the reader’s attention that binge drinking was major problem on many college campuses. Wechsler aims to convince readers that binge drinking is a problem that needs to be stopped. Some of Wechsler’s statements made in this text were persuasive while others were opinions. Wechsler begins this essay by introducing a study conducted at Harvard School of Public Health about drinking patterns in a significant number of American college students (Wilhoit and Wechsler 20-23). By placing this study and some of its results in the text it helped set the mood for the text. As a reader it made me feel as if Wechsler knew what he was talking about and researched his topic at hand. Also with him putting that into his text it helps add to his and the texts credibility. This instance is not th e only instance that Wechsler used in his text. Wechsler placed more recent studies after his initial one to help support it. Shortly after that Wechsler went on to discuss the center of binge drinking which are fraternities and sororities on college campuses (Wilhoit and Wechsler 20-23). This statement Wechsler made is an opinion but a logical opinion. Fraternities and sororities host parties where a lot of alcoholic beverages can be readily available.
